� What is AoE all about?

� Advantages vs Disadvantages

� Our approaches and viewpoints

� Introducing AoE enabler

� Why AoE enabler

What is AoE

� ATA over Ethernet protocol

� A SAN technology

� Networked block storage

� CORAID is the pioneer of AoE

� World’s first SoC done by Layerwalker

� Utilized standard MAC header of IEEE 802.3 Ethernet frames

� No TCP/IP

� Native in Linux kernel 2.6.11 or later

Who wants AoE?

� Consumer/professional

� AoE enabler + eSATA external hard drives

� 50Mbps access performance

� ease of use, like USB or 1394 drives

� SOHO/SMB

� RAID over Ethernet

� Shared storage for server pool

� Shared storage for workstations

� Nearline storage

Advantages of AoE

� H/W Cost

� SATA HDD

� SAN

� Infrastructure cost

� Extra cost of GbE network is 0

� Efficiency of performance & easy config

� No TCP/IP

� Less complex of packets

Disadvantages of AoE

� Very limited H/W solutions available� Coraid EtherDrive

� DIY a Linux machine

� High cost 3rd-party drivers� Lack of affordable commercial SAN FS

� Without SAN FS, write access is constrained to single use at a time to avoid conflict

� S/W, H/W Service providers are difficult to enter the market� Number of platforms in SMB segment is small

� Few consumer applications
